    nobody answered because your post is vague. laughing at us is not going to help either. simple "bump for help" post would have suited fine.
    personally, i didn't see this post yet.

    Since i'm in a good mood, i'll try to help you out.

    First, is the ecu throwing any codes? if the ohms where wrong, the signal should be fubar, and thus throwing a code. its possible that it wouldn't until it got to vtec engagement point (5k ish) while driving.

    what does vtec need to work?

    certain oil pressure (on non-jdm models)
    certain engine coolant temperature
    certain speed from the VSS
    certain load acording the MAP sensor
    certain TPS voltage, so that the ecu thinks you are accelerating and actually need vtec.

    assuming the car warmed up fully, and you have oil and running normal pressure, i'm going to ask if you are throwing any codes for the vss, tps, or the map.

    Ohms should read between 14-30. Are you throwing a CEL? If so, and you're only reading 11.7 ohms, the diagnoses is replace vtec solenoid. I'd try a known good one first to eliminate a grounding issue, then move on to replacing parts.

    A better idea than being a unpatient, as B mentioned, would be to at least try to give some info maybe like what ECU you're using, what model you car is, what you did for the conversion (did you have to do a dpdfi to mpfi conversion?), etc...
